MFA blocks the overwhelming majority of password-based attacks. Here is how to roll it out without frustrating your staff.
Passwords alone no longer protect an organization. Multi-factor authentication (MFA) requires a second proof of identity, so a stolen password is not enough for an attacker to get in.
Start with the accounts that matter most: email, remote access, financial systems and administrator accounts. Use an authenticator app or hardware key rather than SMS where possible, and pair MFA with Conditional Access policies in Microsoft 365 so trusted, managed devices see fewer prompts.
Rolling MFA out in phases, with clear communication and a short training session, keeps disruption low while closing the most commonly exploited door in your environment.
